+-- | PURPOSE  : Example SQL script that demonstrates how to create tables       |
+-- |            containing a CLOB datatype in Oracle8. One of biggest           |
+-- |            differences between creating a CLOB in Oracle8 and Oracle8i or  |
+-- |            higher is the use of the INDEX clause within the LOB clause     |
+-- |            declaration. In Oracle8 it is possible to name the LOB INDEX    |
+-- |            and declare a tablespace and storage clause for it. With        |
+-- |            versions Oracle8i and higher, it is still possible to name the  |
+-- |            INDEX LOB SEGMENT using the INDEX clause but these versions of  |
+-- |            Oracle (8i and higher) will simply ignore  anything else within |
+-- |            the INDEX clause (like tablespaces and storage clause.) From    |
+-- |            what I have read Oracle is deprecating the tablespace and       |
+-- |            storage clauses from being used within the INDEX clause.        |
+-- | NOTE     : As with any code, ensure to test this script in a development   |
+-- |            environment before attempting to run it in production.          |
